Spotter in a Hurry Nearly Led To ‘Slap Snap Shoot’ Explosion
2024-11-09
A spotter in a hurry almost caused a ‘slap, snap, shoot’ explosion at a Western Australian mine site, according to the latest Significant Incident Report from Resources Safety.
The incident at the unnamed mine occurred during a blasting operation when a spooled downline lead become tangled in the rear protection bar of a mobile processing unit (MPU) when the vehicle moved forward. The spotter with miner lamp on head had already moved forward to the next row of drill holes to prepare for loading and did not see the lead start to get tangled.
In this incident the downline lead stretched until it snapped. Fortunately, the detonator did not initiate.
“Snap, slap and shoot” is possible when signal tube detonator plastic tubing is stretched to snapping point. When the plastic tubing recoils after snapping, percussive slapping can initiate the thin layer of high explosives contained within the plastic tube and cause the detonator to fire (or shoot).
The Incident Report says the direct cause of the incident was the design of the MPU’s rear protection bar which allowed the downline lead to become entangled. A contributory cause of the incident was the position of the spotter.
The Report goes on to say, “Mine operators are reminded of the importance of maintaining safe work practices for all charging tasks. They should ensure that:
equipment is designed or modified to eliminate the risk of entanglement where a task requires a spotter, this person is positioned where they can observe the safe and unhindered movement of equipment.

West Virginia coal miner killed in power haulage accident
2024-11-09
CHARLESTON, W.Va. (AP) — A coal miner was killed on the job in northern West Virginia earlier this week, Gov. Jim Justice announced Friday.
William "Joe" Crandall was killed in an incident at Arch Resource's ACI Tygart Valley Mine in Taylor County, West Virginia, on Monday. Crandall is the second worker to die as a result of a mine accident in the last month in the coal-producing state.
A 33-year-old woman died in July after being injured at the Wyco Surface Mine, near the border of Raleigh and Wyoming counties.
"It surely is honorable, but it's a tough business, and we should be so respectful and thankful of our miners every day," Justice said at a news briefing Friday, adding: "Joe Crandall died trying to make your lives and my life better. We should always remember that. Please keep him in your prayers."
Monday's accident involved power haulage, which is equipment such as shuttle cars, scoops, locomotives and front end loaders, mining lamps according to the U.S. Mine Safety and Health Administration.

At least 20 killed in armed attack on miners in Pakistan
2024-10-12
At least 20 miners were killed, and seven others injured, after unidentified gunmen attacked a coal mine in Pakistan’s southwestern province of Balochistan, according to police reports quoted by local media.
The attack took place in the mineral-rich Duki district of Balochistan, a region that borders both Afghanistan and Iran.
The attackers stormed the miners’ accommodations late Thursday night, rounded up the workers, and opened fire, police official Hamayun Khan Nasir said, according to The Express Tribune.They also fired rockets and grenades, damaging mining equipment and some mining headlamps before fleeing the scene.
The assault has sparked widespread condemnation, with authorities launching a manhunt for the perpetrators.
So far, no group has claimed responsibility for the attack, which is the deadliest in weeks.
The violence comes just days before a major security summit in Pakistan’s capital, Islamabad, and as the country hosts a Saudi delegation interested in mining investments .
It also coincides with the signing of $2 billion worth of agreements between Saudi and Pakistani businessmen for investments in various sectors, including mining.
Balochistan, rich in oil and minerals, has long been a hotbed of separatists. These groups accuse the federal government of exploiting the province’s resources without benefiting local communities.
Several of their attacks have been directed at migrant workers, many of whom are employed by smaller, privately run mines.

Twelve people trapped deep underground at Colorado mine rescued after 6 hours
2024-10-12
Twelve people were trapped 1,000 feet (300 meters) underground in a former Colorado gold mine for about six hours on Thursday before a malfunctioning elevator was repaired, enabling them to safely return to the surface, officials said.
The elevator was carrying a separate group of tourists when it malfunctioned about halfway down the mine shaft at the Mollie Kathleen Gold Mine, a tourist attraction in Cripple Creek, Colorado.
One person wearing miner lamp died and four others suffered minor injuries as a result of the malfunction, Teller county sheriff Jason Mikesell told reporters without explaining the cause of death.
The elevator was stuck briefly until it was able to return to the surface with 11 people aboard, he said.
Meanwhile, 11 other tourists and one tour guide remained stuck further below the surface until the elevator was repaired. When that was done six hours later, they were brought back four at a time.
“They’re all in good spirits. We fed them pizza. That’s what they wanted,” Mikesell said.
The repair avoided the need for a rescue plan that would have involved dropping a harness down the mine shaft with a rope and bringing people up one at a time.
The Colorado Springs Fire Department said it was on hand with crews that are specially trained for such a rescue.
Emergency responders had radio communication with the people while they were trapped, and they had water, blankets and chairs to keep them comfortable.
But they were not told someone in the other tour group had died in order to avoid anxiety, Mikesell said.
Cripple Creek is about 45 miles (72 km) from Colorado Springs, through mountain roads near the Pikes Peak summit in the southern Front Range of the Rocky Mountains.
A family business has operated tours at the Mollie Kathleen mine for more than 50 years, with only one previous safety incident in which people were trapped in the elevator in 1986, Mikesell said.
